<DIV class=plugin_output><BR><B>Synopsis:</B><BR>The remote web server
uses a version of PHP that is affected by multiple
flaws.<BR><BR><B>Description:</B><BR>According to its banner, the
version of PHP installed on the remote host is older than 5.2.7. Such
versions may be affected by several security issues : - File truncation
can occur when calling 'dba_replace()' with an invalid argument. - There
is a buffer overflow in the bundled PCRE library fixed by 7.8.
(CVE-2008-2371) - A buffer overflow in the 'imageloadfont()' function in
'ext/gd/gd.c' can be triggered when a specially crafted font is given.
(CVE-2008-3658) - There is a buffer overflow in PHP's internal function
'memnstr()', which is exposed to userspace as 'explode()'.
(CVE-2008-3659) - When used as a FastCGI module, PHP segfaults when
opening a file whose name contains two dots (eg, 'file..php').
(CVE-2008-3660) - Multiple directory traversal vulnerabilities in
functions such as 'posix_access()', 'chdir()', 'ftok()' may allow a
remote attacker to bypass 'safe_mode' restrictions. (CVE-2008-2665 and
CVE-2008-2666). - A buffer overflow may be triggered when processing
long message headers in 'php_imap.c' due to use of an obsolete API call.
(CVE-2008-2829) - A heap-based buffer overflow may be triggered via a
call to 'mb_check_encoding()', part of the 'mbstring' extension.
(CVE-2008-5557) - Missing initialization of 'BG(page_uid)' and
'BG(page_gid)' when PHP is used as an Apache module may allow for
bypassing security restriction due to SAPI 'php_getuid()' overloading.
(CVE-2008-5624) - Incorrect 'php_value' order for Apache configuration
may allow bypassing PHP's 'safe_mode' setting. (CVE-2008-5625) - The
ZipArchive:extractTo() method in the ZipArchive extension fails to
filter directory traversal sequences from file names.
